Background And Aim: Among several noninvasive evaluation methods of portal hypertension (PH), the measurement of spleen stiffness is a reliable method for predicting esophageal variceal bleeding; however, the underlying mechanisms for increased stiffness remain unclear. We attempted to elucidate the pathological changes to the spleen and the underlying mechanisms in patients with PH.

Methods: Histological examination was performed using splenic tissues from 42 patients with PH who underwent laparoscopic splenectomy, and the results were compared with those from patients without PH.

Background: A bronchobiliary fistula, an intercommunication between the biliary tract and bronchial trees, is an extremely rare complication after hepatectomy.

The immediate postoperative clinical course was uneventful, but the patient was febrile and laboratory examinations revealed leukocytosis on the 15th postoperative day.

Background & Aims: Splenectomy in cirrhotic patients has been reported to improve liver function; however the underlying mechanism remains obscure. In the present study, we investigated the mechanism using a murine model, which represents well the compensated liver cirrhosis.

Methods: C57BL/6 male mice were allowed to drink water including thioacetamide (TAA: 300 mg/L) ad libitum for 32 weeks.

Primary squamous cell carcinoma (SCC) of the liver is rare tumor with an unfavorable prognosis. We report a case of advanced primary SCC of the liver arising adjacent to a nonparasitic liver cyst, invading into the right diaphragm and the right lung tissue. Contrast-enhanced ultrasonography (CE-US) demonstrated unique enhancement in the late vascular phase, which was incompatible with those observed in hepatocellular carcinoma, cholangiocellular carcinoma, or metastatic adenocarcinoma.
